be inthe form of a rotar;7 disk suitably drivenand timed with respect tothe piston of the engine, whereby the working parts of the valve and itsmechanism will be ma# terially reduced and valve vibration eliminated.

Another obj ect of the invention is the provision of means foreffectually lubricating the valve and contiguous parts, so that wear dueto friction will be reduced to a minimum.

Another object of the invention is the provision of novel means formounting the valve and for providing a compression-proof contact withthe valve seat.

lith the above and other objects in view, the invention further includesthe following novel features and details of construction, to

'd5 be hereinafter more fully described, illustrated in the accompanyingdrawings and pointed out in the appended claim.

In the drawings lFigure 1 is a vertical sectional view 3U through aportion of the cylinder of an `internal combustion engine with theinvention applied.

Figures 2 and 3 are sectional views taken respectively on the lines 2-2and 3--3 of V Figure 1.

Figure 4 is a fragmentary section on the line 4 4 of Figure 3.

Figure 5 is a detail perspective View of the packing member. i

Referring to the drawings in detail where- Y in like characters ofreference denote corresponding parts, the reference character indicatesa portion of an engine cylinder and 11 the water acket, while the pistonis indicated at l2 and the spark plug at 13.

`Communicating lwith the interior of the cylinder 10 through a Vcommonport 14, are in-V V takey and exhaust ports 15 .and 16 respectively.These ports are. divided by apartition 17 and may be suitably connectedwith fz splurce of fuelsupply and an exhaust mani- O 'r1 V- Extendingtransverselyf` ofthe ports between the inner ends ofk theports. 15.and16 and the adjacent endofthe port 14, is a valve chamber 18., Thischamber is extended as n shown at 19 and accommodates aV rotary disk"valve 20. f This valve is provided with spacedv inner, outer andintermediate ring flanges 21,`

22and 21 respectively, .and these flanges are communicate with passages24 which extend diametrically throughthe valve;V These pas` tricallywith the valve casing, so that* the e0Y providedV withlubricatingpassages 23 which shaft 26 extends transversely` through thevcasing.Y By kreference* to Figure 2,y ofthe drawings `1t will be seenthat the inner ring iiange 21Y and the outer ring flange 22 (extend:

In order to provide a will open and close leakproof seat for the valve20 around the ports 15 and 16, the

invention provides a packingblock ineinber which vi'sprovided withspaced openings 31 and 32. In close proximity to the intake and exhaustports 15 and 16 the casing is provided with lateral and longitudinalcommunieating recesses or depressions 31ljfor the reception of the sidesand ends vof the packing block,;.whilethe `4partition 17 hasv its upperportionwidenedfand formed with a transverse depression 52 to receivetherein the 4 transverse Wall 53 provided bythe spaced openings 31 and32 in theblock'.
